I've never really encountered anything that would indicate they are too strict.

The thing to bear in mind is that tone matters, a lot - I don't think many people would report, and I don't think GMs would necessarily action on the basis that you simply told someone their strategy was inefficient or whether you gave constructive feedback on how to improve, e.g., "can you use your AoEs for trash pulls, we'll do more damage and it'll help us clear the dungeon quicker"

However, you would probably find yourself getting 'cozy' with a GM if you were more blunt. e.g., "Dude, stop sucking at the game".

I think the guidelines don't necessarily convey the 'tone' adequately enough which gives people a sense of fear of interacting in a public space. - But I would say in my little tinfoil hat those that have the most fear with this are often those that either:
a) Don't understand the importance of tone when speaking
b) Don't care and try to use it as a scapegoat. - People can have very selective memory when it comes to situations that have them being sanctioned or accused. - e.g.,

Person A - "Why was I banned? I only said and did xyz"
Person B - "Can you post a screenshot of the log?"
*Screenshots demonstrate that xyz wasn't said, or at the very least was inferred in a lot more a disrespectful tone than initially suggested.

In fact, I'm fairly sure many of these policies were no different to how they initially were - But were instead just expanded to include examples/clarification - I know a very common strand of feedback with their ToS way-back was that they were too vague. - All they did was simply remove that 'vagueness'
